Hi there! I understand you're having trouble with the reward claim button in the DomiNations app not working. Let's see if we can get that fixed together.

To start, can you tell me a bit more about your situation? For example:
- Are you using the game on your Windows device through a browser or the app?
- Does the claim button appear but simply doesn't respond when clicked, or is it greyed out/unresponsive?
- Have you tried any steps so far to fix it, like refreshing or restarting the game?

In the meantime, here are some common fixes that work well on Windows browsers like WebKit for game issues like this:

1. Clear your browser cache: Sometimes old data can cause buttons to misbehave. Clearing cache can refresh things. Here's how in Windows WebKit browsers:
- Press Ctrl + Shift + Delete at the same time
- Select cached images and files (and optionally cookies)
- Click Clear Data

2. Refresh and restart: After clearing cache, refresh the page or close and reopen your browser. Log back into DomiNations and try claiming the reward again.

3. Check your internet connection: A slow or unstable connection can cause buttons to hang. Try switching networks if possible.

4. Try a different browser or device: If possible, log in from a mobile device or a different browser to see if the issue continues.

5. Make sure your game or browser is up to date: An outdated version can cause functionality problems.

If those don’t work, a few community users have found a temporary workaround by pressing a "share" button nearby (if available) and then quickly going back to the reward screen, which sometimes refreshes the state.

Let me know what you've tried and what you notice when clicking the claim button. We can dig deeper from there!

Are you satisfied with the solution I provided so far?
